Roof Hatches, sometimes called an access hatch, provide easy access to a roof or deck and allow the user to have a weather proof door for quick access to any roof. A Roof Hatch is typically designed to provide access to the roof of a building so equipment may be serviced or replaced and is often required to meet certain specifications or building codes. Roof hatches can be installed in both residential and commercial applications, even though they are most often seen in commercial applications. Consider Roof Hatches from Bilco, JL Industries and Acudor.
